HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 782,595, dated February14, 1905.

f' Appiicaiion ined May 12, `1904. serai No. 207,635.

To all whom it mmy/ concern:

Be it known that I, WILLIAM .IAM Es BULGER, J r., a citizen of theUnited States, residing at ouverneur, in the county of St. Lawrence andState of New York,.have invented new and useful Improvements inHose-Couplings, of which the -following is a specification.

, This invention has relation to hose-couplings; and it consists in thenovel construction and arrangements of its parts, as hereinafter shownand described.

The object of the invention is to provide a simple and effective means-for joining two sections of hose together or a section of hose to aplug.

The coupling consists of two members, the end of one of which is adaptedto slip in the end of the other. The male member is provided with anexterior flange, against which is located a gasket which is adapted toengage the end of the female member. The female member is provided withexterior lugs.

A sleeve is located upon the male member and is provided at one end withan adjustable screw-threaded plug` and at its other end with a fiangehaving recesses adapted to permit the entrance of the lugs of the femalemember behind said ange. A'Ihe said sleeve is provided withlever-operated eccentrics which are adapted to engage the ange of themale member and impi-nge the gasket between said flange and the iend ofthe female member.

In the accompanying drawings, Figure 1 is a side elevation of thecoupling. Fig. 2 is a horizontal sectional view of the same. Fig.

3 is an end view of the sleeve, and Fig. 4 is alperspeotive view of thelever and eccentries.

The female I'nember 1 is provided with the eXteriorly-located lugs 2 2.The said member 1 may be connected to the end of a section of hose or toa plug. ber 3 is provided with the eXteriorly-located flange-4. .Theinner end of the member 3 is adapted to slip in the inner end of themember 1. The end of the hose-section 5 is attached to the outer end ofthe section 3. The plug 6 surrounds the section 3 and is screwthreadedinto the sleeve 7. Said plug is provided with the fiange 8, in which islocated a notch 9. The end of the-sleeve 7 is provided The male memwitha similar notch 10. The spring 11 surrounds' the plug 6 and is providedwith bent ends adapted to enter the notches 9 and 10. Thus the said plug6 may be locked into p0- sition with relation to the sleeve 7; but byremoving the-spring 11 the said plug may be turned andv adjusted back orforth in the end of the sleeve 7. The gasket 12 surrounds the member 3and bears against the flange 4 and the inner end of the member 1. Theannulus 13 is located within the sleeve 7 for the purpose of keeping thegasket 12 in its proper position when `the members 1 and 3 areuncoupled. The other end ofthe sleeve 7 is provided with aninwardly-extending flange 14, which in turn is provided with therecesses 15, which are of suflicient size to permit the lugs 2 2 to passtherethrough and slip behind said ange. The sides of the sleeve 7 areprovided with the elongated openings 16, having the enlarged portions 17located at their rear ends. Through the said enlargements 17 theeccentrics 18 are passed, and the shank 19 thereofmay slip into theopenings 16. The said shanks 19 are connected together by the lever 20.

To couple the members 1 and 2, the levern 2O is elevated in the positionas shown in heavy lines in Fig. l.- The inner end of the member 1 ispassed through the inner end of the sleeve 7, and the inner end of themember 3 is slipped into the inner end of the member l. The sleeve 7 isthen given a quarter-turn, which brings the lugs 2 2 behind the flange14. The lever 2O is then forced down into the position as shown by thedotted lines in Fig. 1. This kmovement of the lever causes theeccentrics 18 to describe a partial rotation. The said eccentricsbearing against the fiange 4 force the gasket 12 against the end of themember 1 and the coupling is effected. To uncouple the members, theoperation above described is reversed.

The object of making the plug 6 adjustable with relation to the sleeve 7is to compensate :tor the gaskets 12 of different thicknesses.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, isl l'. A coupling consisting of male and female IOOmembers, an exterior flange located on one said member, exterior lugslocated upon the other said member, a gasket located between said flangeand the end of one of the members, a sleeve attached to one member andhaving a recessed flange adapted to pass beyond the lugs of the othermember, lever-operated eccentrics attached to said sleeve and adapted toengage the flange of the flanged member on the side thereof opposite thegasket.

2. A coupling consisting of male and female members, an exterior flangelocated on one said member, exterior lugs located upon the other member,a gasket located between said flange and the end of one of the members,a sleeve attached to one member and having a recessed flange adapted topass beyond the lugs of the other member, an adjustable plug located insaid sleeve, lever-operated eccentrics attached to said sleeve andoperating between said plug and the flange of the flanged member.

3. A coupling consisting of male and female members, an exterior flangelocated on one member, exterior lugs located upon the other member, agasket located between said flange and the end of one of the members, asleeve attached to one member and having a recessed flange adapted topass beyond the lugs of the other vmember, an adjustable plug located inSaid sleeve, a means for locking said plug in position with relation tosaid sleeve, lever-operated eccentrics attached to said sleeve and'operating between said plug and the flange of yof the other member,said sleevehaving an abutment, said sleeve having side openings withenlargements, eccentrics having shanks passing through said openings, alever connecting said Shanks together, said eccentrics operating betweenthe flange of the flanged member and the abutment of the sleeve.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
